Answer: a=2/5b + 1/5c (I may have answered your question but idk if I did)

Step 1: Add -4a to both sides.

9a−2b+−4a=4a+c+−4a

5a−2b=c

Step 2: Add 2b to both sides.

5a−2b+2b=c+2b

5a=2b+c

Step 3: Divide both sides by 5.

5a/5=2b+c/5

a=2/5b+1/5c

Answer:

A

Step-by-step explanation:

To sovle this we must combine the numbers togther and the variables togther.

We have:

8c+6-3c-2

Lets take out the c's and combine them:

8c -3c

=

5c

Now lets take out the numbers:

6-2

=

4

Now lets put these back together and we get the expression:

5c+4

This looks like A.

Hope this helps! :D

seropon [69]

Answer:

Larry places 19 puzzles

Step-by-step explanation:

Step one:

given data

let the number of puzzles Larry places be x

and let the number of puzzles Drew places be y

so

y=3x-11

Step two:

We are told that Drew places at least 10

so for x= 10

y= 3*10-11

y=30-11

y=19
